The retired aircraft carrier USS America is on the bottom of the Atlantic Ocean, sunk by the Navy in a series of explosive tests that upset some veterans. No warship this size or larger had ever been sunk, and plans to sink the America caused controversy.

"Not a day goes by that I don't think about it," said Lee McNulty, president of the USS America Foundation, which wanted to turn the ship into a museum. "Of all the carriers, that one should have been saved, just for the name America."
